Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, and in particular relates to a vehicle-mounted camera connector. Background Technology

[0002] Existing automotive camera FAKRA connectors and back covers are mostly integrated, forged from aluminum alloy, such as the automotive connector with publication number CN218525802U. The complex FAKRA connector structure leads to a complex forging mold structure, resulting in a short mold lifespan. Furthermore, after forging, CNC machining of features like holes is required, making the process complex, the production cycle long, and the production cost high. The integrated FAKRA connector has a fixed insertion angle; if the insertion angle needs to be adjusted according to customer requirements, a new mold must be created, making it difficult to flexibly meet diverse customer needs. Therefore, a separate back cover was designed. Different FAKRA colors were required for different interfaces, necessitating a plastic FAKRA connector. Combining two different materials significantly increased the difficulty. Traditional methods, even after improving the guide opening size, became unsuitable and limited the size of the guide opening itself. Utility Model Content

[0003] Based on the above-mentioned technical problems, this utility model proposes a vehicle camera connector that uses a split outer conductor design to connect the Fakra head to the rear shell, without limiting the size of the opening at the tail of the outer conductor.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A vehicle-mounted camera connector, comprising:

[0006] A connector includes a hollow first outer conductor, a second outer conductor, and a central pin extending along an axial direction within the hollow interior space, the central pin being fixed within the first outer conductor by an insulator; an outer housing located outside the connector includes a rear housing with a receiving cavity and a connector, the connector being fitted onto a pre-set mounting hole on the outer surface of the rear housing; wherein the second outer conductor is inserted from the receiving cavity into the mounting hole and engages with the first outer conductor extending from the outside of the rear housing into the mounting hole.

[0007] Furthermore, the first outer conductor has a larger diameter abutment on the side near the second outer conductor, the end of the first outer conductor has several outwardly flared joints, and the end of the second outer conductor has an inwardly folded edge. When the first outer conductor and the second outer conductor are connected, the joints are pressed onto the folded edge from the inside of the second outer conductor using a dotting process to make the two join together.

[0008] Furthermore, the mounting hole of the rear shell is located inside the receiving cavity and a limiting platform is provided on one side. A flange is provided around the outer periphery of the second outer conductor, and the flange abuts against the limiting platform.

[0009] Furthermore, the connector is a Fakra connector that directly mates with the vehicle body plug-in connector.

[0010] Furthermore, the bottom of the connector is provided with a positioning plate, and the outer side of the outer panel where the mounting hole is located is provided with a positioning groove. The positioning plate abuts against the positioning groove, and the shape of the positioning groove is the same as the shape of the positioning plate.

[0011] Furthermore, the mating head is provided with several positioning strips and snap fasteners that engage with the mating connector.

[0012] Furthermore, the joint gap between the first outer conductor and the center pin, and the joint gap between the second outer conductor and the rear shell, are both filled with sealant.

[0013] Compared with the prior art, the beneficial technical effects of the vehicle camera connector provided by this utility model are as follows:

[0014] This invention divides the outer conductor into two parts. The fixed connection between the first and second outer conductors clamps the back shell and the connector from the front and back. The two outer conductors are assembled and then assembled by a dotting process, which also simplifies the assembly process and improves production efficiency. Since the second outer conductor is inserted into the metal back shell from the back, the size of the guide opening at the tail of the second outer conductor is not limited. Furthermore, the use of sealant provides better waterproofing. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] This utility model provides a vehicle-mounted camera connector, including an outer housing and a plug. Specifically:

[0026] like Figures 1-4 As shown, in this embodiment, the outer housing includes a rear shell 10 with a receiving cavity and a connector 20. The connector 20 and the rear shell 10 are independent parts. The connector 20 is assembled onto a pre-set mounting hole 102 on the outer panel 101 of the rear shell 10. The connector 20 is a FAKRA head, which serves as a connector for direct mating with the vehicle body plug-in connector (the female end of the vehicle body wiring harness, not shown in the figure). Its outer side wall is provided with a positioning insert 202 and a snap fastener 203. Preferably, the insertion end of the connector 20 also has an inner chamfer. The positioning insert 202 and the inner chamfer can play a positioning and guiding role when the connectors at both ends are mated, thereby ensuring the mating accuracy of the connector. The snap fastener 203 can make the FAKRA head engage with the plug-in connector, ensuring a reliable connection of the camera connector.

[0027] like Figure 4As shown, a positioning plate 201 is integrally formed at the bottom of the connector 20. The outer contour of the positioning plate 201 is a circular or centrally symmetrical regular shape, such as a square or regular polygon with chamfers. The back shell 10 is made of metal material, which can effectively eliminate electromagnetic interference, play a shielding role, and improve the quality of signal transmission. In order to axially limit the connector 20 and provide sufficient holding force to prevent the connector 20 from falling out of the back shell 10 during the pulling process, and at the same time improve assembly efficiency, a positioning groove 1020 with a certain depth is formed around the mounting hole 102 on the outer panel 101 of the back shell 10 (i.e., the contact surface with the connector 20). The shape of the positioning groove 1020 is the same as the shape of the positioning plate 201, so that the positioning plate 201 can be embedded into the positioning groove 1020 at any installation angle, flexibly meeting the needs of customers for different docking angles.

[0028] like Figures 1 to 6 As shown, the connector includes a hollow first outer conductor 60, a second outer conductor 30, and a center pin 40 extending axially within the hollow internal space. The center pin 40 is fixed within the first outer conductor 60 by an insulator 50. The first outer conductor 60 and the second outer conductor 30 are integral zinc die-cast components manufactured by die-casting. As the outer conductors of the coaxial connector, they provide effective electromagnetic shielding for internal signal transmission. Figure 5 As shown, a T-shaped limiting platform 1021 is provided inside the receiving cavity 103 of the rear shell 10 along the periphery of the mounting hole 102. A flange 301 is provided around the outer periphery of the second outer conductor 30, and the flange 301 abuts against the limiting platform 1021. The second outer conductor 30 is inserted from inside the receiving cavity 103 into the mounting hole 102 and engages with the first outer conductor 60 inserted from outside the rear shell 10 into the mounting hole 102. See details [link to relevant documentation]. Figure 6 The first outer conductor 60 has a larger diameter abutment 601 on the side near the second outer conductor 30. The end of the first outer conductor 60 has several outwardly flared joints 602. The end of the second outer conductor 30 has an inwardly folded edge 302. To ensure sufficient holding force, the abutment 601 is close to the end face of the second outer conductor 30, and the joints 602 are pressed onto the folded edge 302 from the inside of the second outer conductor 30 by a dotting process to combine the two (that is, the joints 602 are formed into dotted joints on the folded edge 302 by mechanical stamping).

[0029] The center pin 40 serves as the inner conductor of the vehicle camera connector, transmitting signals. Furthermore, the center pin 40 is made of brass and is coaxially positioned within the first outer conductor 60. An insulator 50 fills the space between the first outer conductor 60 and the center pin 40, with both ends of the center pin 40 protruding outside the insulator 50.

[0030] like Figure 3 and Figure 4As shown, to prevent the connector from loosening and leaking air after repeated insertion and removal, sealant 70 is filled at the joint gap between the first outer conductor 60 and the center pin 40, and at the joint gap between the second outer conductor 30 and the rear shell 10. The sealant 70 is applied using a dispensing process to seal the joints, which is not only more efficient in production than using a sealing ring, but also allows for more comprehensive contact with the gaps. This invention, by employing this double-sealing structure, provides better waterproofing.

[0031] The specific installation steps for the vehicle-mounted camera connector in this embodiment are as follows:

[0032] 1. Press the insulator 50 and center pin 40 assembly into the first outer conductor 60, and fix it at four points after pressing;

[0033] 2. After marking the product, insert the connector 20 from the front, and then put the whole thing into the back cover 10;

[0034] 3. Install the second outer conductor 30 on the back cover 10 and then mark the dots;

[0035] 4. Let the dotted product stand still.

[0036] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
